     On June 30, 1941, the German Wehrmacht conquered Lviv in Ukraine. On June 30, residents of Lviv searched among the bodies of people killed by Soviet military authorities in the city's prison for their relatives. Auxiliary units of Ukrainian nationalists carried out mass shootings of Jewish citizens immediately after the German conquest of Lviv.

     During the first days of the German attack on Soviet forces, anti-Jewish violence erupted in Lviv. The city was plunged into hatred sown by ideological conflict and inflamed by the crimes of the Soviet regime. On June 30, 1941, Lviv was occupied by units of the German Wehrmacht and the Nachtigall Battalion, composed primarily of fighters from Stepan Bandera's Ukrainian nationalist organization (OUN-B). After the Red Terror of the Soviet occupation that began in 1939, Ukrainians in particular welcomed the German army and its subordinate Ukrainian units. The German Wehrmacht delegated the registration of Jews and their separation from Aryans to the Ukrainian nationalists. The Wehrmacht then subjected the Jews to forced labor.

     The discovery of thousands of bodies of victims massacred by the Soviet NKVD in three prisons in Lviv triggered the mass killings. The Holocaust in Eastern Europe, directed by the German military, began after accusing Jews of being Bolsheviks. From June 30, after the German occupation, mass violence against Jews erupted on the streets of Lviv. While pogroms were carried out on the streets in collusion with the Ukrainian police, German military units had already begun executions in prisons where Jews were working. The violence peaked on July 5, when approximately 2,000 Jews were shot in various locations throughout the city.
